Westpac has set for itself an ambitious goal: to be the "best digital bank" in New Zealand, if not the world. Based on some of its latest tests with Google Glass, iBeacons and smart watches, the bank has a shot at the title. We spoke with Simon Pomeroy, Westpac New Zealand's chief digital officer, about some of the technology he's piloting.

What does it mean to be the world's best digital bank?

Delivering consistent online service across all platforms, predominantly through the mobile phone, will separate us from [other] banks we're seeing.

How do you think people will bank with Google Glass in the future?

It's a great question. I think the customer will decide. It will come down to the capability of the device and how people choose to use it. The greatest analogy I can use for this is around mobile phones, how people were using them five years ago and how they're using smart phones now. No one was banking on a mobile phone then [five years ago], and now 35% of our customers are using them every day to bank.

The answers around Google Glass and wearables will really be customer driven. Customers want faster, easier ways of doing things. We see that now in all facets of life. CashTank is a great example of an app we built for mobile where customers can get their balances with a tap on an Apple or Android device. We see that being a real opportunity for wearable devices, whether it's a watch or Google Glass. But I also think things like notifications, about account balances or when a payment is due to go out, are great things to use on Google Glass or smart watches. Also being able to do things like find the nearest ATM or the nearest branch, being able to make a payment or transfer between your accounts. Those are things that customers want to be able to access quickly.

Do you put fraud alerts in that category, too?

For me, it's all the transactional things customers want. We give our customers the ability to set up alerts and notifications around a whole range of banking needs. To be able to have that notification come in in real time to your Google Glass or your smart watch or to your mobile phone, really gives customers more control.

In the U.S., Google Glass made a big impression when it first came out and then it became something for nerds. A lot of people here feel wearable computing has got to be trendy and fashionable rather than something that labels them as an ultra-geek. What're your thoughts?

It's probably not that dissimilar from a smart watch. At the moment you have Google developing the [Glass] capability and Samsung and Sony in the smart watch space. I think if customers adopt this technology, you'll see more designer brands entering the market. You can see a world where while Google Glass might seem geeky to some people at the moment and not in the hands of mainstream customers, in 10 years you could have High Street shops selling Google Glass or some other technology built into everyday specs. We're at the cutting edge at the moment, but it won't take long, particularly in mobile, for this new technology to become mainstream.

What is happening with Westpac's smart-watch trial?

We put the CashTank app on a Sony smart watch, and we're about to drop it into a Samsung smart watch as well. We've been using the technology in house to test its capability. At this stage, we've limited it to the balance inquiry. The reason we wanted to try it on the watch was to see how easy it is to develop on the device. We're building technology and applications that are very scalable across different devices really quickly and easily. We put the smart watch app together in less than a week, and the Google Glass app will probably take a shorter length of time.

How do you make such projects happen and how do you get the funds to do them?

We've got a philosophy that what we're trying to do is ultimately drive customer value, improve service for customers, making it easier, giving more capability to customers to do more of their banking with us. We're looking at the customer and saying, what would this do for a customer if we adopted it? Then we start listening to customers about what they want, how they want to access it, what devices they want to be using. And we look at international development. The smart watch, Google Glass, and iBeacon are good examples where we're seeing international media and business attention on these things.

Expect banks to pull back on energy lending in the near term, as regulators step up their scrutiny of oil loans and bankers approach the business with a "different attitude," says Mariner Kemper, chairman and chief executive at UMB Financial in Kansas City, Mo.

The post-election rise in stock prices has been a boon for investors, but it is also causing notable changes for financial institutions. Here are a number of ways that the rally can help  and hurt  the banking industry.

It's the time of year to give thanks, and for bankers some things to be grateful for include rising stock prices, a brightening M&A outlook and, most notably, the potential for regulatory relief under President-elect Donald Trump. Here is a list of developments the industry might be celebrating this Thanksgiving holiday.

Bankers are anxiously waiting to see who President-elect Donald Trump will pick as the next Treasury secretary. Several prominent names have been floated for the job, though with every passing day, a new possible choice seems to pop up. Following is a look at the current crop of candidates and their chances.

Mobile phones are only going to become a bigger part of how banks interact with their customers, so several institutions are looking to enhance that experience. They are focusing on better ways of opening accounts, verifying identities, interacting with customers and offering new services and features. Here are some of the improvements announced this year.

This year federal and state regulators have started to pay closer attention to the rapidly evolving online-lending sector  particularly online small-business lending. What follows is a look at eight key players in the debate over how to regulate this emerging industry.
